此外，包裝機(jī)械行業(yè)逐漸加入機(jī)器視覺功能，對PC-Based運(yùn)動控制需求也逐步增加。有業(yè)內(nèi)人士指出，未來PC-Based運(yùn)動控制器的應(yīng)用領(lǐng)域?qū)M(jìn)一步擴(kuò)大，部分PLC市場會向PC-Based市場轉(zhuǎn)移。
為此，倍福董事總經(jīng)理梁力強(qiáng)表示，倍福中國會繼續(xù)宣傳和推廣基于PC的開放式控制系統(tǒng)，著力開拓戰(zhàn)略性新興產(chǎn)業(yè)，包括鋰電設(shè)備、電子制造和半導(dǎo)體、倉儲和物流行業(yè)以及國家重點(diǎn)發(fā)展的高端裝備制造業(yè)。
PC-Based的發(fā)展，對于PLC無疑是挑戰(zhàn)，此前有人預(yù)言PLC將逐步退出工業(yè)自動化的歷史舞臺，不過過去10年內(nèi)，超小型和小型PLC的性能獲得了極大地提高，產(chǎn)量也大幅增長。
PC-Based控制器陣營中，除研華、華北工控、研祥等工控機(jī)生產(chǎn)廠商外，目前PC-based運(yùn)動控制產(chǎn)品市場中，國產(chǎn)廠商固高、眾為興、雷賽等在運(yùn)動控制卡這一細(xì)分領(lǐng)域占據(jù)主導(dǎo)地位。
而在嵌入式控制器及軟PLC這兩個細(xì)分市場上，以倍福、貝加萊、CODESYS為代表的外資廠商仍然占據(jù)著主要的市場份額。當(dāng)然，國內(nèi)也有一些基于PC技術(shù)的控制器企業(yè)，其中包括華成工控、納博特、人通智能等。
他們認(rèn)為，未來嵌入式技術(shù)將會被廣泛應(yīng)用于PAC，成為自動化系統(tǒng)的重要技術(shù)之一。
在用戶和系統(tǒng)集成商之間，對于PAC的質(zhì)疑同樣存在：PAC相對于PLC來說價(jià)格高、可靠性低、可拓展能力差，還有人認(rèn)為，PAC并沒有真正針對某種迫切的或者潛在的市場需求，因此不免曲高和寡。
有部分反對者則認(rèn)為，PAC技術(shù)發(fā)展趨向，如統(tǒng)一的多專業(yè)開發(fā)平臺、通信技術(shù)等也會對PLC的技術(shù)發(fā)展施加有益的影響。
值得一提的是，除了上述提到的PLC、PC-Based和PAC之外，針對行業(yè)應(yīng)用，機(jī)器人專用控制器成為國內(nèi)多數(shù)廠商布局的重點(diǎn)，特別是像埃斯頓、華中數(shù)控、配天機(jī)器人等這樣以機(jī)器人本體研發(fā)為主的企業(yè)。
